915nm 60Watt Free Space Output IR Laser System
This time we bring a 915nm high power semiconductor laser. The bottom of the laser module is equipped with a heat sink. Aluminum heat sink and cooling fan can effectively prolong the continuous working time of high-power lasers. There are three working modes of CW/TTL/Analog on the power supply for selection.
The power of 60W is very high power, which can instantly ignite the cardboard. Be sure to pay attention to safety when operating, the operator must wear laser protective glasses, and the laser cannot point to other people or other flammable objects. The rotary button on the power supply can adjust the working current, thereby adjusting the output power.
915nm infrared laser is invisible light, which is invisible to the human eye. Here the laser can easily ignite the cardboard.

915nm 3W IR MM Fiber Coupled Laser System
Usually we often see visible lasers, but few people will test infrared invisible lasers. Today we tested a 915nm infrared laser and its output power of 3000mW. Then when it is coupled through the fiber, what is the output power of the fiber end? Let’s check it now.
The optical fiber can be customized. 100μm~1000μm fiber is optional, the coupling efficiency of different fibers will be somewhat different. The larger the core diameter, the higher the coupling efficiency, usually the coupling efficiency is 80%~90 percent. In addition, the fiber length and interface also can be customzied. Here is 1000μm, SMA interface fiber.
The output power of the laser is adjustable from 0 to 3000mW, which can be adjusted by the knob. It supports 3 working modes, CW/TTL/Analog, switch the working mode on the back of the laser power supply. In TTL/Analog modulation mode, an external modulation signal needs to be connected.

To adjust the output power by adjusting the working current:
Turn the ‘Adjustor’ knob clockwise, when the current exceeds the minimum working current, the Laser indicator light turns green, and there is laser output at this time. When the ‘Adjustor’ is rotated clockwise to the end, it is the max working current and the max output power of the laser. In addition, the red STOP button is used for emergency stop, and it is not used under normal circumstances.
532nm DPSS Laser VS 520nm Semiconductor Laser
532nm and 520nm are both common green lasers in the laboratory. The difference is that one is a diode pumped solid state(DPSS) laser and the other is a semiconductor laser.
532nm is a commonly used wavelength in dpss laser. DPSS lasers have advantages in compactness and efficiency over other types, and high power DPSS have replaced ion lasers and flashlamp-pumped lasers in many scientific applications, and are now appearing commonly in green and other color laser pointers.
The choice of the semiconductor material determines the wavelength of the emitted beam, which in today’s laser diodes range from infra-red to the UV spectrum. Laser diodes are the most common type of lasers produced, with a wide range of uses that include fiber optic communications, barcode readers, laser pointers, CD/DVD/Blu-ray disc reading/recording, laser printing, laser scanning and light beam illumination. With the use of a phosphor like that found on white LEDs, Laser diodes can be used for general illumination.
